Mfr/8858 IIWEIVTOR ATTORNEYS sTArns'P CAN-NOZZLE PLUG-SEAL.

Application filed June 4. 1913.

To all whom it we 03 concern:

Be it known that I, FERDINAND WETTER- nnnc, a citizen of the UnitedStates, and a resident of Perth Amboy, in the county of Middlesex andState of New Jersey, have invented a new and Improved Can-NozzlePlug-Seal, of which the following is a full, clear, and exactdescription.

My invention relates to plugs for can nozzles and has reference moreparticularly to plugs for varnish cans, having means which seal the plugin the nozzle of the can.

An object of the invention is to provide a simple, inexpensive andeasily removable plug which has means for sealing the nozzle of a can.

Theinvention consists of the construction and combination of parts to bemore fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which like characters indicate correspondingparts in all the views and in which:

Figure 1 is an elevation of a can embody: ing my invention; Fig. 2 is asection in elevation through same; Fig. 3 is a longitudinal sectionthrough the blank; and Fig. 4 is a plan viewof same.

In using varnish great trouble is experienced with the nozzle of the canafter the seal, as at present used, is removed from the nozzle. The airhaving access to the varnish after removal of the seal dries the samerapidly, particularli where the varnish is in a thin layer, as forexample, in the nozzle after pouring out some of the varnish. The dryingof varnish in a nozzle greatly reduces the aperture in the same andtherefore the nozzle must be cleaned, which is not an easy taskto dowithout injuring the varnish in the can. To obviate this defect I haveinvented a seal for use in connection with varnish cans.

The can 5, as shown in the drawings, is provided with a nozzle 6,preferably of circular cross section and slightly diverging toward themouth of the nozzle, so that the nozzle represents a frustum of a conewith the larger base forming the mouth of the nozzle. The nozzle 6 atthe mouth is provided'with a reinforced border 7. Fitting snugly intothe nozzle is a plug 8 having a concentric cylindrical portion 9normally Specification of Letters Patent.

projecting above the reinforced portion 7 of the nozzle.

A blank 10 engages the cylindrical portion 9 by means of a centralorificell. The blank 10 is in diameter larger than the reinforcedportion 7 of the nozzle and is concentric with the same when fitted onthe cylindrical portion 9 by means of the open ing 11. The blank 10 isalso provided with a tongue 12, so that when the border of the blank 10is crimped about the reinforced portion 7, of the nozzle the blankforces the plug 8 into the nozzle 6, making a tight fit between the plugand the nozzle, while the tongue 12 is bent simultaneously against theexterior lateral surface of the nozzle 6. To prevent sticking betweenthe plug 8 and the nozzle 6 a paper cup 13 is fitted on the plug; also,to make a perfect seal by means of the blank 10, the same is lined withasuitable layer 14 of paper or any other material.

When a can of varnish is sealed by means of a device as hereindisclosed, the same is opened as follows: The tongue 12 is bent awayfrom the exterior lateral surface of the nozzle and by means of it theblank 10 is pulled ofi from the reinforcing portion 7 of the nozzle, theplug 8 still remaining in the nozzle. The plug 8 can then be removed bysimply pulling the cylindrical portion 9, and due to the provision of apaper layer, the same can easily be removed from the nozzle. Thenecessary amount of varnish can then be poured out of the can and theplug restored to its position. This Will keep the air out of the can andalso prevent the formation of a coat of varnish in the nozzle aperture.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

1. The combination with a can nozzle of a plug engaging the nozzleopening and a blank engaging said plug and nozzle and whereby said plugis locked in the nozzle. a

the nozzle and having a portion projecting above the nozzle; a blankhaving means engaging said portion'of the plug projecting above thenozzle and the reinforced portion of the nozzle whereby the said plug islocked in the nozzle with said portion projecting through the nozzle;and a tongue rigidly associated with the blank and normally disposedadjacent the exterior lateral surface of the nozzle and whereby theblank can be removed from the nozzle and the plug.

4:. The combination of a can nozzle diverging toward its mouth andhaving a reinforced border at the mouth; of a plug comprising a conicalportion fitting snugly into the nozzle and a cylindrical portionconcentric with the conical portion and projecting above the nozzlesmouth; a blank FERDINAND WETTERBERG.
